Spiny lobsters are normally nocturnal animals.
They leave their dens on coral reefs or rock crevices at dusk
and forage in the surronding sand and seagrass habitats. Around
sunrise they return home and spend most of the daylight hours
hidden from view.Many young lobsters also appear to be nomadic.
Tagging studies have revealed the some lobsters wander hundreds
of kilometers over many months.

In addition, some spiny lobster populations
undertake long migrations on a seasonal basis. Lobsters form
long lines called queues which stretch across the ocean floor. These mass
migrations may last several days with lobsters walking both night
and day. Despite encountering changing currents and seafloor
topography the lobsters usually continue marching in straight
lines.
